7 '0 all whom it may concern Be it known that I, AooLrH Soaunwuu, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful improvements in Counter-Pressure Begulators, of which the following is a specification.

The present invention relates to'a counterpressure regulator Which operates to main-- tain a proportionate degree of pressure between two chambers, and is especially ada table for use in oon unction with bottlelling machines, where it is desired to maintain a differential degree of pressure within an air chamber and a liquid chamber, although, of course, the device is not necessarily limited for use with this particular mechanism, or necessarily in conjunction with an air and liquid chamber.

The principal objects of the present iuven'tion are, to provide a mechanism which is under all conditions and at all times automatic in its operation, which is compact in form and arrangement, and which is simple of operation and cheap of manufacture.

A further object of the invention is to provide a series of yielding surfaces which form a part of the regulator mechanism and which are effected by changes in pressure, and to so arrange these surfaces that they may be interchanged or others substituted for them, whereb Y any ratio or square area between said s'ur aces may be obtained, and hence any differential pressure between the pressure chambers can be had.

The invention further consists in the features of construction and the combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a sectional view of the regulator'of the present invention; and Fig. 2 is a section taken on line 2-42 of Fig. 1.

As heretofore stated, this mechanism is especially applicable for use with bottle filling machinery. In the art ofbottlefilling, it is necessary, during the filling operation, to place the liquid under a pressure eration. This operation is 'well known in the art otf bottle-filling machines and need not be discussed in detail in the present ina cap 4 and at its lower end by a cap I. Entered into the cap 5 in the construction shown is a pipe (3 leading from a chamber containing liquid under pressure, or other pressure chamber. Entering in o the casing is a conduit 7 leading from fa second pressure chamber.- In bottling apparatus this second pressure chamber is the air tank; and a third conduit 8 is provided, which leads from a source of pressure supply. The con duit 8 enters into the casing at the point where a bridge member 9 joins the interior walls of said casing. This bridge member, as shown in Fig. 1, extends from side to side of the casing in one direction, and, as shown in Fig. 2, lies tree from the sides of the casing in the other direction. t is in the nature of a web or bridge, and is not a partition in the sense that it divides the casing at this oint into two separate chambers. This bridge member is provided with a passageway 10 and a passageway 11. The passageway 10, as shown in Fig. 1, is in communication with the conduit 8 and opens to the upper side of the bridge 9; and the conduit 11 is in communication with an exhaust passage 12 at one end, and at its other .svhich, as shown in Fig. 1, is adapted to seat within the open end of the passage 10; and thebody of the strap-like member is provided with a tapered plug 17, the end of which is adapted to seat within the open end of the passage 11. By making one plug screw-threaded and adjustable, av greater or lesp degree of movement canbe allowed the strap-like member, as-Will be apparent from a study of the drawing.

iucross section, closed at its upper end by 7 pressure within the chamber 20.

Positioned below the bridge member 9 is an upper partition wall 18 and a lower partition wall 19, both, as shown, in the form of a diaphragm member. These partitions divide the interior of the casing into an upper chamber 20, into which air from the conduit 7 passes, and a lower chamber 21, into which air from the conduit 6 passes. Botlr of these diaphragms, as shown, are joined to the body portion of the strapdlke member 13, and each of the diaphragms, as shown, is securiedin position by independent screw-threaded clamping rings, this construction enabling the diaphragms to be removed and others substituted therefor without disturbing the general arrangement of the equalizing mechanism.

Thebody portion of the member 13 terminates in a stem 22, around which is placed a collar 23 bearing against the diaphra m 18; and an interiorly screw-threaded col ar 24 is placed on the lower end of the stem to retain in position the diaphragm 19. The diaphragm 19 is acted upon solely by the pressure withinthe chamber 21, and the iaphragm 18 is acted upon solely. by the As shown the diaphragm 18 is of larger area than the diaphragm 19, and hence will be actuated by a less pressure than the diaphragm 18. This will result in a differential pressure being established within the chambers when the diaphragms are in equalized conditibn, that is, when the pressure on one is equal to the pressure on the other, whereby the strap-like member is maintained in neuwtral purposes of illustration, 1'

position. For mightsay that ve pounds of pressureacting upon the diaphragm 19 willexert a cor tam pressure upon said diaphragm, and that a six pound pressure act, g upon the diaphragm 18' will exert the same pressure upon this diaphragm. The pressute on the diaphragms will then be equalized and movement of the strap-like member prevented. Thus, a difi'ercnti'al pressure is maintained within the respective chambers, sin the pressure per square inch in the chamber 21 exceeds the pressure per square inch in the chamber 20..

- l i. In case it is deemed desirable to change the ,dill'erential pressure existing between the chambers, this can be readily accom plished by the substitution of diaphragms of different sizes from those illustrated, the

' size and arrangement of the diaphragmsbe ing dependent upon the difference in pressure which it is desired to obtain, and the variance in square area between the diaphragms depending upon the difference in pound pressure between the chambers desired.

The operation is as follows: Pressure is admitted through the conduit 8 from the source of essure supply until sufiicient pressure is accumulated within. the chamber 20 to counteract the force of the pressure within the chamber 21 acting upon the diaphragm ,19. lVhen this is accomplished, the parts will be in the position shown in Fig. 1, and-there will be a steady passage of alr from the conduit 8 into the chamber'20. and a passage of air from the chamber 20 through the outlet conduit 12, maintaining a fixed degree of pressure within said chamher. The inletting of pressure and the exhausting of pressure under these circumstances willnot be very great, that is, the opening around the valves is somewhat exaggerated in the drawing from what it would be in actual use. If a 1 pressure should accumulate in the chamber 21 inexcess of the amount desired, it will force the diaphragm 19 upward, causing the tapered plug 17 to seat within the open end of the passage 11, and thus cut oil the exhaustingof pressure from the chamber 20; and since both the plugs 16 and 17 are carried by the strap-like member, an upward movement of the plug 16 will take place simultaneously with the upward movement of the plug 17. This upward movement of the plug 1b will open the passage 10 and admit pressure from the conduit 8 into the chamber 20.

Such admittance will continue until the pressure within the chamber 20 is sufficient I to lower the diaphragm 18 and the straplike niember 13 and reverse the position of the valves witll-respect to the bridge 9, or

bring them to the equalized condition heretofore referred to.

If an excess pressure should occur within the chamber 20, it will act upon the diaphragm 18 to lower it, thus lowering 'the strap-like member 13,,unseating the tapered plug 17, and seating the plug 16, thus cutting off the flow of pressure into the chamber 20 and exhausting the pressure from said chamber. And this operation will continue unt l the proper equalization of pressure between the chambers 20mm! 21 is brought about.

.From the foregoing description, it will be observed that the equalizer of the'prosent invention is at all times automatic in its operation and does not depend upon the actuations of the valve, levers, or other contrii'ances. Y
